>> How do they make tables with only CSS without using HTML Tables?
Well, if you need a table, you need a table. But you can do typical table layout stuff with CSS pretty easily. Just make good use of divs.

>> is it possible to make a table as shown on the screenshot below with only CSS and NO HTML?
Absolutely! You can do it a bunch of ways. Probably the easiest would be something like this.

Then the CSS is a simple div with carefully crafted borders and a float for the "title" element. Then inside the div is just a bullet list with a cut left margin and link below it with a large left margin.
